Elbox: Mediator PCI 4000

The Mediator PCI 4000 is essentially a bridgeboard designed for use in
the A3000 and A4000 which makes your PCI slots active, if you have
them. Although it's normally supplied with the various A4000 and A3000
Mediator PCI busboards, it can in theory be used with busboards
supplied my other manufacturers containing Zorro III and PCI slots
where the PCI slots are not active. In the very early days of PCI for
the Amiga, several replacement busboards were built for the Amiga but
often the PCI slots were not active and so require a bridgeboard such
as this to be of any use. It requires at least one Zorro III and PCI
slot inline. The card is capable of supporting up to 5 PCI slots (PCI
2.1 compatible) with a 66/33Mhz clock. It supports the full 4GB PCI
address space, busmastering and the SDRAM/SGRAM on PCI graphics cards
being used as a fast DMA buffer. Up to 6 Zorro III slots can be used
simultaneously with the PCI slots.
